There should be a link to this article or the content should be included in the storage section of the TrueNAS doc site.
This was exactly what I was looking for. I am migrating from SATA based workstations to a storage bridge bus (SBB) based Supermicro 6036ST-6LR two node system. The SAS2008 based card is in IR mode but running older (11.0) firmware. I didn't want to migrate to the IT firmware unless required because the RAID HBA is packaged onto the motherboard and has proprietary connections to the midplane. Looks like I just need to upgrade the firmware to 20.00.07.
What brought me here? I see all of the disks in `camcontrol devlist`, I get unique serial numbers when enumerating them with `camcontrol inquiry <disk> -S`. I can add disks to ZFS vdev's in FreeBSD 13.0, but TrueNAS 13-U3 doesn't show any available disks. I was nearly confident I was going to have to go to IT firmware to get FreeNAS to show them as available, and I am unsure if I will be able to use the (Supermicro noted as required RAID functionality) without IR firmware when sharing access between the two nodes to the same storage with RSF-1-HA. It now looks like I just need FW 20.0 on the
I will follow up with edits for any issues I run into... just wanted to share my appreciation for this article.
While I cannot promise any particular result, I would note that historically, it's been fine to use true LSI IR firmware -- not vendor hacked-up firmware -- in place of the IT code. I have machines as recent as TrueNAS 12 running IR cards and they're fine. I would just try running IR fw 20.00.07.00 and see if that works out.
